What to do

  1. Update to the latest version (2.20.5). Anything older than 2.20.5 has at least one known issue listed below. Dashboard → Updates, or Plugins → “update now”.
  2. If you cannot update right away, deactivate it until you can.
  3. Turn on auto-updates for it: Plugins → “Enable auto-updates” on its row.
  4. If you ran a vulnerable version and something looks off (spam pages, strange admins, redirects), run the free scan.

With WP-CLI: wp plugin get ultimate-addons-for-gutenberg --field=version shows what you run; wp plugin update ultimate-addons-for-gutenberg updates it.

Details from the advisory

The Spectra Gutenberg Blocks – Website Builder for the Block Editor plugin for WordPress is vulnerable to limited file deletion due to insufficient file path validation in the '__construct' function in all versions up to, and including, 2.20.4 This makes it possible for unauthenticated attackers to delete theme files on the server.

Details from the advisory

The Spectra Legacy – Gutenberg Blocks plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.20.0 via the editor_assets function, which exposes the uag_insta_linked_accounts option through the uagb_blocks_info object without a capability check. This makes it possible for authenticated attackers, with Contributor-level access and above, to extract sensitive data including raw Instagram Graph API access tokens configured by an administrator. Exploitation requires the Spectra Pro plugin to be active with a linked Instagram account.

Access needed (per CVSS)

Range from
CVE record (the advisory publisher) · score by CISA ADP
Details from the advisory

The Spectra Legacy WordPress plugin before 2.20.0 does not validate or escape several block style attributes before using them to build the CSS it outputs on the front end, allowing users with the Contributor role and above to inject arbitrary CSS into the pages that render the affected block. The injected styles are served to anonymous visitors of those pages and can force external resource loads, deface/redress the page, or exfiltrate data via CSS attribute selectors. JavaScript execution is not possible at this role (the script-tag breakout is removed by KSES), so the impact is limited to CSS injection.

The Spectra Gutenberg Blocks – Website Builder for the Block Editor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `uagb/image` block in all versions up to, and including, 2.19.28 due to insufficient input sanitization and output escaping.

The Spectra Gutenberg Blocks – Website Builder for the Block Editor plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 2.19.25. This makes it possible for authenticated attackers, with Contributor-level access and above, to execute code on the server. Exploitation requires a two-block payload embedded in post content: the first block registers a fake uagb/-prefixed block type with an attacker-specified render_callback, and the second block of the same fake type triggers invocation of that callback via call_user_func() during sequential block rendering in the same page request.

The Spectra Gutenberg Blocks – Website Builder for the Block Editor plugin for WordPress is vulnerable to Information Disclosure in all versions up to, and including, 2.19.17. This is due to the plugin failing to check `post_password_required()` before rendering post excerpts in the `render_excerpt()` function and the `uagb_get_excerpt()` helper function. This makes it possible for unauthenticated attackers to read excerpts of password-protected posts by simply viewing any page that contains a Spectra Post Grid, Post Masonry, Post Carousel, or Post Timeline block.
